A. (incorrect) The client probably will be placed on fluid restriction. Fluids should not be encouraged for a client with a low sodium level (135-145 mEq/L).
B. (incorrect) Hypertonic solutions of saline are 3% to 5%, not 10%, because of the extreme nature of hypertonic solutions. Hypertonic solutions of saline may be used but very cautiously because if the sodium levels are increased too rapidly, a massive fluid shift can occur in the body, resulting in neurological damage and heart failure.
C. (incorrect) THe antidiuretic hormone (vasopressin) would cause water retention in the body and increase the problem.
D. (correct) Clients with sodium levels less than 120 mEq/L are at risk for seizures as a complication. The lower the sodium level, the greater the risk of a seizure.
TEST-TAKING HINTS: The test taker must memorize certain common lab values and understand how deviations in the electrolytes affect the body.
